Note: 1.If the ground is too hard, do not twist or hammer it with force. Try to soften the ground with water and then insert into the ground. Failure to follow this may result in product damage. 2.It is suggested the solar panel to be fully charged for 12h at the first use. 3.The light will light up automatically at dusk and may turn off automatically when ambient light is too strong(above 15lux). 4.Turn the light on and set light mode before charging the solar power, so it will light up at dusk.
